What is the maximum upload size for the file picker?

For some reason, when I upload a 40MB video, the upload is interrupted with a CORS error.
It seems to be possible to upload a smaller sized video.

Yes this is a bug. I raised a ticket about 1 and a half week ago - developers are aware apparently and will update. Until then only small files can be uploaded - which is a pain if you want to use 3rd party storage as you will need the temporary URL

Thanks for the reply.
I was just having trouble because I was able to upload before.
I’m glad to hear that the bug is on its way to being resolved.
